Ergonomics essentially means designing the workplace to maximize productivity by reducing user fatigue and discomfort. As we all know, people vary greatly in size. We also know that many of our call center employees spend most of their day at a computer.  This means that they have a serious risk for developing musculoskeletal disorders such as carpal tunnel. 

 

Both of these facts mean that computer workstations need to be adjustable to fit many different types of users to make them more comfortable and productive while working at their computer.

The main piece of adjustable ergonomic equipment that may help to prevent musculoskeletal disorders, such as carpal tunnel, is an adjustable keyboard mechanism.

  

A properly adjusted keyboard is an essential part of the ergonomic work environment. It is commonly known that correct keyboard positioning and use can help to decrease carpal tunnel syndrome and make working at a computer workstation more comfortable for the user. There are many studies that state one case of carpal tunnel syndrome can cost an employer up to $35,000 per claim, so although the initial investment for these accessories may seem sizable, it will pay off in the long run.

 

 

There are recommendations for proper ergonomic keyboard placement. The first recommendation is for keyboard height. The keyboard should be located at a height that allows the worker to type with upper arms hanging relaxed from the shoulders and the elbows at roughly right angles to allow the wrists to be fairly strait. Second is keyboard distance. The keyboard should be placed in a position that will allow the worker to maintain a neutral posture while typing. Regarding tilt, the keyboard tray should have a slight negative tilt to keep wrists in a neutral posture.

It is also important not to forget about mouse placement when considering keyboard placement. It is recommended that the mouse should be placed at the same height as the keyboard and as close to the keyboard as possible, for operation without reaching. Along with the keyboard, the mouse tray should have a slight negative tilt to keep wrists in a neutral posture.

Also, take advantage of standing height mechanisms. The most ergonomically correct workstations encourage individuals to change positions frequently and easily. With the correct tools, standing is as simple as sitting.

 

A height adjustable work surface is one way to move from a sitting to standing work position. Another, perhaps easier way, is to use a keyboard tray and monitor arm with enough adjustment to be used while in a standing position.

If a user does have the option to work while standing, the worker should use proper positioning. The proper position for a standing working position is when the user's legs, torso, neck, and head are approximately in-line and vertical. The user may also elevate one foot on a rest while in this posture.

To summarize, the adjustable keyboard mechanisms benefits – a keyboard mechanism in the correct position can reduce the chance of carpal tunnel syndrome, makes workers comfortable and productive, adjusts to fit a multitude of users, and some models may also help to create a standing workstation.

 

With these elements in place, workforces can ensure a productive, safe work environment while also saving on long term costs and employee compensation costs.
